so there is another very big problem with Harpoon – what the hell is the latest version from which version? Is my HCE 2009.050 the last and same version of HCE included with HUE? Which is the version number of Classic Harpoon shipped with HUE?

Please post an exact (graphical) version tree – this is better than thousands of web pages trying to explain the complex Harpoon history with words. I would do this on my own, but I haven’t the necessary information.
